Conventional surfactants are molecules that include both polar and non-polar groups in the same molecules that are able to change the properties of the liquid in which they are solubilized.They are low molecular weight(<500 g mol-1)molecules and start to form aggregates in water known as micelles.The surfactant concentration at which these micelles are formed is known as critical micellar concentration(CMC).The non-polar hydrophobic groups are oriented inwards in the micelles forming a hydrophobic environment.The polar groups reside in contact with water.Depending on the nature of the polar groups,they can be classified as anionic,cationic,non-ionic or zwitterionic.
